' BELT-QLACING moon.

Be it known that we, Ismon M.'JA( JOBS and WILLIAM CRAMER, citizens ofthe United States, residing, respectively, at the city of Kansas City,in the county of Jackson and State of Missouri, and at the city of St.

Louis, State of Missouri, have invented certain new and usefulImprovements in Belt- Lacing Tools, of which the following is aspecification. I

. This invention is a tool for applying belt lacings to belts. It isespeciallyintended and adapted for use in connection with a well-kriownand standard form of staples used for belt lacings.

An object of the invention is to provide a tool which can be constructedat a minimum cost, and which will be eflicient in use.

A further object of the invention is to provide a tool in which the beltis securely clamped against displacement so that the staples will beproperly placed therein.

A further object is to provide slmple clamping means to hold the belt,and also the staples. p

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur,

Figure 1 is a top plan view;

Fig. 2 is a side elevation;

Fig. 3 is a side elevation with a hammer about to clench the staples;

Fig. 4 is a longitudinal vertical sectlonal view;

Fig. 5 illustrates a staple in a piece of belting;

Figs. 6 and 7 illustrate a modification; and

Figs. 8 and 9 depict another modification.

The staples 1 are placed in the jaw 2 having a plurality of teeth 3. Theend of the belt 4 is then passed between the upper points 5 and thelower points 6 of the staples 1, and between the wedge 7 and the keeper8. The wedge 7 is driven. home. The pin 9 is inserted as soon as thestaples 1 are inserted in the jaw 2. 7

With the parts in the position shown in Fig. 3, the ordinary hammer 10is used and clenches the staples 1 into the shape shown in Figs. 5and 1. 0

After this, a twill of twisted rawhide or the like (not shown in thedrawings) is Specification of Letters Patent.

passed through openings 11 in all the staples -1 causing them to meettogether and overlap from opposite pieces of belting brought to- "getherend to end. a

The teeth 8 are preferably formed by saw cuts alongthe bend of aU-shaped plate 12 and a'plate 14 is so disposed between the arms of theU-shaped plate 12 as to provide or anvil 15 by rivets 16 or. othersuitable means. 1

The jaw .teeth 31 hold the staples 1 quite in Figs. 6 to 9 is to afforda brace for them so that they will be more steadily held. Such brace orsteadyingdevice takes the form in Figs. 8 and 9 of the wedge 16, which,when driven home as shown in Fig. 8, holds the staples 1 very firmly andsteadily while the same are being hammered by hammer 10.

The said brace'or steadying device in Figs. 6 and 7 is in the form of athumbnut 17 which applies pressure to plate 12 and causes the same topress the lower part of the staples against the plate or anvil 15.

In Figs. 6 and 7 the anvil or plate 15 is shown as provided with anintegral upturned front portion 18 which cooperates with a clamp 19pivoted at 20 on a pin 21 that runs through a bend of the anvil15 tohold the belt a, thereby preventing dis placement of the same during thestapling operation. In use, belt 4 will be'fed be tween the upturnedportion 18 and the strap 22 of clamp 19. Plate 12, in Figs. 6 and 7especially, is more or less resilient and therefore responds to theaction of the thurnbscrew 17, thereby causing the teeth 3 to press uponthe staples 1, holding the same steady.

The thumbscrew 17 consists of the winged nut 28, the screw 24, and theclamping member 25, the latter being adapted to press on rod 26 thatextends from one side to the other of the clamp 19. Turning nut 23 downon screw 24 causes clamping member 25' to press on rod 26 and thus toclamp the belt between clamp 19 and the upturn 18.

It is to be understood that the constructions depicted in Figs. 6 and 7and 8 and 9 can be united in one, that is to say, wedge 16 may be placedin the device illustrated in Figs. 6 and 7.

steadily for the impact of the hammer 10, but the object of themodifications depicted Having thus described this invention, We herebyreserve the benefit of all changes in form, arrangement, order, or useof parts, as it is evident that many minor changes may be made thereinwithout departing from the spirit of this invention or the scope of thefollowing claims.

e claim:

1. A belt lacing device comprising a plate having staple receivingmeans, a staple retaining pin passed through said plate, a clampingdevice engaged with said plate ,to hold the staple retaining pin inposition a Urshaped belt holding member having a cross rod engaged bysaid clamping device, and tensioning means for said clamping device.

2. A belt lacing device comprising a plate having staple receivingmeans, a staple retaining pin passed through said plate, a clampingdevice engaged with said plate to hold the staple retaining pin inposition,.a U-shaped belt holding member having a cross rod engaged bysaid clamping device, tensioning means for said clamping device, and ananvil supporting said plate.

8. In a belt lacing device, the combination signatures.

of a U-plate having teeth at its bend, and arranged to hold staplesbetween the teeth, a removable pin securing the staples within theU-plate, a member'arranged to'advance along an inclined plane to clampsaid staples against displacement, means to hold the belt tion, a beltholding means to securely hold belt against displacement and inoperative relation to the staples, said belt holding means operated bysaid screw clamp, and an anvil on which the staples are to be clenchedin said belt. i

In testimony whereof we hereunto affix our isin on M. JACOBS. VVlW.CRAMER.
